- ENALAPRIL-NITROXYDERIVATIVES DERIVATIVES AND RELATED COMPOUNDS AS ACE INHIBITORS FOR THE TREATMENT OF CARDIOVASCULAR DISEASES
-
Compounds of formula (I): A-(X1-ONO2)S wherein A is a known ACE-inhibitor such as enalapril and X1 is a spacer such as a (C1-C6)-alkylene. The complete definition of A and X1 is given in claim 1. The compounds can be used as ACE-inhibitors for the treatment of cardiovascular and renal diseases and inflammatory processes. The example of formula (1) has an improved pharmacological activity when compared with the structurally closest related prior art compound.

- SYNTHESIS OF N-ALKYL-1,2,4-OXADIAZINONES AS ANGIOTENSIN-II (AT1) RECEPTOR ANTAGONISTS
-
4-Alkyl-1,2,4-oxadiazinones were prepared by regiospecific alkylation of the corresponding 4H-oxadiazinones, which were synthesized by a trimethylaluminium mediated cyclization reaction.Alkylation was regiospecyfic and generally facile; in one example, however, an unusual fragmentation reaction occurred.A homochiral oxadiazineone was also prepared and alkylated under the described conditions. 4-Biphenylmethyl-1,2,4-oxadi-azinones were potent angiotensin-II receptor antagonists.

- Angiotensin-Converting Enzyme Inhibitors: Perhydro-1,4-thiazepin-5-one Derivatives
-
α-amino>-5-oxoperhydro-1,4-thiazepin-4-yl>acetic acids (monoester monoacids) and their dicarboxylic acids having the hydrophobic substituents at the 2- or 3-position of the thiazepinone ring were prepared and assayed for angiotensin-converting enzyme (ACE) inhibitory activity.The dicarboxylic acids having the pseudoequatorial amino groups at the 6-position and the pseudoequatorial hydrophobic substituents at the 2- or 3-position of the chair conformation of the thiazepinone ring had potent in vitro inhibitory activity.The monoester monoacids having the hydrophobic substituents at the 2-position suppressed pressor response to angiotensin I for a longer duration than those having the substituents at the 3-position when administered orally.The structure-activity relationship was studied by conformational energy calculations of the thiazepinone ring.

- The Design and Synthesis of the Angiotensin Converting Enzyme Inhibitor Cilazapril and Related Bicyclic Compounds
-
The postulated binding functions for the active site of Angiotensin Converting Enzyme (A.C.E.), derived in an earlier study, have made possible the design of improved inhibitors.Consequently, (1S,9S)-9-octahydro-10-oxo-6H-pyridazodiazepine-1-carboxylic acid (Cilazapril), and related compounds, have been synthesized.They are very active inhibitors of A.C.E. and are highly potent antihypertensives in vivo.

- A FAVOURABLE DIASTEREOSELECTIVE SYNTHESIS OF N-(1-S-ETHOXYCARBONYL-3-PHENYLPROPYL)-S-ALANINE
-
N-(1-S-Ethoxycarbonyl-3-phenylpropyl)-S-alanine is prepared by Michael addition of S-alaninebenzylester to ethyl-4-oxo-4-phenyl-2-butenoate in a regio- and diastereoselective fashion and subsequent catalytic hydrogenolysis.
